Abstract:

The availability of inexpensive hardware such as CMOS cameras and
microphones has fostered the development of Wireless Multimedia Sensor
Networks (WMSNs), i.e., networks of wirelessly interconnected devices that
are able to ubiquitously retrieve multimedia content such as video and
audio streams, still images, and scalar sensor data from the environment.

In this talk, the state-of-the-art in algorithms, protocols, and hardware
for wireless multimedia sensor networks is surveyed, and open research
issues are discussed in detail. Architectures for WMSNs are explored,
along with their advantages and drawbacks. Currently off-the-shelf
hardware as well as available research prototypes for WMSNs are listed and
classified. Existing solutions and open research issues at the
application, transport, network, link, and physical layers of the
communication stack are investigated, along with possible cross-layer
synergies and optimizations.
